You can absolutely drive and rent a car in Greece using a valid, full driving license issued by any EU or EEA member state. Following EU-wide regulations, a license from one member state is legally recognized in all others without the need for additional documentation. You must be at least 18 years old to drive, though most car rental companies in Greece require drivers to be at least 21 (and sometimes 25) to avoid "young driver" surcharges. Your license must be in the Latin alphabet; if it is not, it is wise to carry an International Driving Permit (IDP) as a translation. When driving in Greece, you are legally required to carry your physical license, your passport or ID card, and proof of insurance at all times. It is important to note that Greek traffic police are strict about seatbelts and mobile phone usage while driving. For those coming from the UK, post-Brexit rules still allow the use of a UK photo-card license in Greece without an IDP, but an EU license remains the "gold standard" for hassle-free travel across the Mediterranean.
